Photocell relays — NPP "VEL"

Photocell relay (dusk switch)

Distinctive features:

Designed to switch street lighting on and off automatically; it can also serve as a light-dependent control element for other equipment.
ФР101 — photocell relay with a solid-state output.
ФР102 – photocell relay with a relay output.
The light-sensing element is a ФД-1 photodiode or an СФ2-5 photoresistor.
The relay has a manual pickup level adjustment.
